“So the Founders supported homosexual marriage, abortion on demand and pornography?”
Where and by which Founders were those issues written of?
Regarding abortion, the colonies operated under English Common Law, which became the bassis for America law.
Under common law, abortion “before quikening” (i.e., before the baby’s movement could be felt) was a misdemeanor and abortion after quickening was a felony. (In the 19th Century as science gained a greater understanding of conception and fetal development the laws was changed to make ALL abortions felonies).
If the founders had disagreed with this and believed that abortion was a right, certainly they would have put that in the Constitution or at least we would have the writings of certain founders arguing for abortion rights.
Regarding same sex marriage, the penalty for sodomy in late 18th Century America was generally DEATH.
The idea of same-sex marriage would be unthinkable to the founders or any other 18th Century American.
